Definitions

  • the invention is also characterized in that at least one of the non-deformable washers comprises on its internal face a central projection, the internal face of which is intended, after clamping, to come to bear against the internal face of another washer.
  • the two non-deformable washers comprise on their internal face a central projection intended, after tightening, to come to bear.
  • the device In order to ensure axial thrust, forcing the separation in the event of the device being loosened, it comprises a spring element arranged between the non-deformable washers. And to allow the positioning and retention of the spring element, at least one of the washers is provided with a circular groove on its internal face, close to the central hole of said washer.
  • Figure 5a illustrates in section the device according to the preferred embodiment of the invention, showing the fact that the tightening is not carried out.
  • the structure can be, for example, a crane and the assembly concerns, for example, two profiles, but the structure can also be a pylon fixed to the ground by means of studs sealed in a concrete block.
  • the invention can relate to all types of structures or assemblies without departing from the scope of the invention.
  • At least one of the non-deformable washers (2a, 2b) comprises on its internal face a central projection (26), the internal face of which (260) is intended after setting to come to bear against the internal face (20a) of the other washer (2a, 2b).
  • the two washers (2a, 2b) have a central projection intended to be in contact with one another.
  • the section of the spring has a flat area advantageously located at the level of the outer diameter of the ring.
  • the deformable ring (3) is made of a solid material and cut in its section to allow diametral deformation.
  • the two washers (2a, 2b) are integral in rotation by means of clipping, gluing or welding, produced by ultrasound or vibration, or even by a mechanical type connection.
